Ultralight dark matter detection with levitated ferromagnets
Saarik Kalia, Dmitry Budker, Derek F. Jackson Kimball +7
Levitated ferromagnets act as ultraprecise magnetometers, which can exhibit high quality factors due to their excellent isolation from the environment. These instruments can be uti…
Levitated ferromagnetic magnetometer with energy resolution well below
Felix Ahrens, Wei Ji, Dmitry Budker +3
A quantum limit on the measurement of magnetic field has been recently pointed out, stating that the so-called Energy Resolution is bounded to $E_\mathrm{R} \gtrsim…
Linear cooling of a levitated micromagnetic cylinder by vibration
Chris Timberlake, Elliot Simcox, Hendrik Ulbricht
We report feedback cooling of translational and librational degrees of freedom of a levitated micromagnet cylinder, utilizing a piezoelectric actuator to apply linear feedback to h…
Probing modified gravity with magnetically levitated resonators
Chris Timberlake, Andrea Vinante, Francesco Shankar +2
We present an experimental procedure, based on Meissner effect levitation of neodymium ferromagnets, as a method of measuring the gravitational interactions between mg masses. The…
Surpassing the Energy Resolution Limit with ferromagnetic torque sensors
Andrea Vinante, Chris Timberlake, Dmitry Budker +3
We discuss the fundamental noise limitations of a ferromagnetic torque sensor based on a levitated magnet in the tipping regime. We evaluate the optimal magnetic field resolution t…
Ferromagnetic Gyroscopes for Tests of Fundamental Physics
Pavel Fadeev, Chris Timberlake, Tao Wang +6
A ferromagnetic gyroscope (FG) is a ferromagnet whose angular momentum is dominated by electron spin polarization and that will precess under the action of an external torque, such…
